How to run the linting on multiple or group of .html or tpl.html files?

By default the linting is only being applied to the first .html or tpl.html file in that path ./src/*/.html and the report looks like this:

"allpassed": false,
"fileschecked": 1,
"filessucceeded": 0,
"filesfailed": 1,
"failed": [{
"filepath": "/project/src/app/cart/shopping-cart.html",
"numerrs": 7,
"errors": [{
"msg": "Start tag seen without seeing a doctype first. Expected e.g. “”.",
"line": 1,
"col": 11
}, {
"msg": "Element “head” is missing a required instance of child element “title”.",
"line": 1,
"col": 11
}, {

}, {

}, {
